std.net.curl應用程序將引發異常

Question

我嘗試從std.net.curl

import std.net.curl, std.stdio; 

void main() 
{ 
    auto range1 = byLineAsync("www.google.com"); 
    auto range2 = byLineAsync("www.wikipedia.org"); 
    foreach (line; byLineAsync("dlang.org")) 
     writeln(line); 

    foreach (line; range1) writeln(line); 
    foreach (line; range2) writeln(line); 
} 

編譯這個程序我編譯這個程序是這樣的。

$ DMD internet.d -ofinternet

或

DMD -I/usr/include目錄/ DMD /火衛一-LL：libcurl.so.4.2.0 internet.d -ofinternet

該程序編譯正常，但它會引發異常。

這看起來像一個錯誤，也許你應該把它報告給https://issues.dlang.org/。

對於異步網絡編程，大多數人會使用Vibe.d，雖然：http://vibed.org/
